Great plug for high HP, high boast application. Awesome price
I've been an NGK plug user for some time, very good product at a reasonable price. The TR series plugs are great for my 1200 HP application. Anyone running a KB 4.2 or Whipple 4.0 or above should really use these plugs. In addition to working great, they caused my golf score to drop by three shots.
